Oil Boiler Isolation Switch.

Zoomup
Evenin' All,


Regarding an external ground sited domestic oil fired boiler for heating and hot water that has an internal switched fused connection unit nearby inside the house, what regulations will require an external electrical isolator adjacent to the oil boiler? You know the sort of thing, a double pole rotary isolator.

    I need to go and sit at my desk and prepare a quote, earlier this week I went to a flat which is electrically heated with an E7 prepayment meter to work out how to reduce the electric bill, which I think can be reduced by at least thirty five quid a week over the winter.


    On the list is replace this useless timer.

    I expect that the timer is o.k. but is just lacking some pins.


    Anyway, I wired up the oil boiler today, much the same as the old one was wired up.


    1. Oil feed pipe main bonded.


    2. Frost stat installed and connected up to Grant boiler circuit board. Set at 5 deg. C.


    3. Programmable room stat left in lounge for ground floor underfloor heating as it has a 5 degree C cut in in case of house frost.


    4. Upstairs left connected to a time switch (as before) via a 2 port valve. Only works when the downstairs underfloor heating is on. Two rads. upstairs with thermostatic rad. valves, and a bathroom towel rail with no thermostatic valve.


    5. Warmth from downstairs naturally rises up the open spiral staircase.


    6. Underfloor heating has a separate pump next to the manifold which runs via the programmable room stat and a small relay, (as before).


    7. Hot water available at all times.


    8. The boiler is very good, quiet and clean burning.
